vbscript skipline and cr line endings

Question

For some reason when I use the objFile.ReadLine method to read my text file, the entire file is returned as one long line. The file I'm opening is using CR line endings instead of CRLF or LF line endings. Does anyone know how I can read this file line by line in vbscript if ReadLine does not recognize CR line endings? Code is below:

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set txsInput = objFSO.OpenTextFile("C:\Path\To\My\File.csv",1)
'Read lines one by one 
Do While txsInput.AtEndOfStream <> True
  strTemp = txsInput.ReadLine
  msgbox strTemp
Loop

Instead of alerting for each line, I get one alert with the entire file. Any help is appreciated.

Answer 1

.ReadLine won't work in your case, because it depends on the existence of a vbLf character. If you don't want to re-encode the line breaks you can do either what Panayot Karabakalov suggested (if the file is large), or read the entire file and split it at vbCr (if the file is not-so-large):

text = objFSO.OpenTextFile("C:\Path\To\My\File.csv").ReadAll
For Each line In Split(text, vbCr)
  MsgBox line
Next

Re-encoding the file can be done like this:

Set fso = CreateObject("Scripting.FileSystemObject")

filename = "C:\path\to\your.csv"

Set infile  = fso.OpenTextFile(filename)
Set outfile = fso.OpenTextFile(filename & ".tmp", 2)

Do Until infile.AtEndOfStream
  c = infile.Read(1)
  If c = vbCr Then
    outfile.Write vbCrLf
  Else
    outfile.Write c
  End If
Loop

infile.Close
outfile.Close

fso.DeleteFile filename, True
fso.MoveFile filename & ".tmp", filename

Or you could use something like recode for the conversion. Most text editors (e.g. Vim, Notepad++, SciTE, UltraEdit, …) can do this kind of conversion, too.

Maybe not the best idea (and not tested) but try this one.

Do Until txsInput.AtEndOfStream
    strTemp = ""
    Do
        strChar = txsInput.Read(1)
        If strChar <> vbCr Then
            strTemp = strTemp & strChar
        Else
            Exit Do
        End If
    Loop
    If Len(strTemp) Then MsgBox strTemp
Loop
